Статья о интеграции dovecot и dspam

Добавим учетные записи для работы с виртуальными почтовыми ящиками

groupadd -g 500 vmail
useradd -g vmail -u 500 vmail
mkdir /var/vmail
chown vmail.vmail /var/vmail

Устанавливаем postfix

apt-get update
apt-get install postfix postfix-ldap

Запустить конфигуратор дебиана

dpkg-reconfigure postfix

При установке пакетов отвечаем на вопросы конфигуратора

• Общий тип почтовой настройки - Интернет сайт
• Системной почтовое имя - daemon.drivesource.ru

Добавляем в основной файл конфигурации /etc/postfix/main.cf

mailbox_transport = dovecot

В конфигурацию транспорта /etc/postfix/master.cf

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}

Устанавливаем dovecot

apt-get update
apt-get install dovecot-common dovecot-imapd

Отредактируем основной файл конфигурации /etc/dovecot/dovecot.conf

# Disable LOGIN command and all other plaintext authentications unless
# SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP
# matches the local IP (ie. you're connecting from the same computer), the
# connection is considered secure and plaintext authentication is allowed.
